The object of my invention is to produce a smelter of simple construction by means of which iron ore, and other ores, may be smelted with a minimum expenditure and waste of 5 fuel.

The accompanying drawing is a vertical sectional perspeetiveof an embodiment ofmy' invention. v p v In the drawing 10, indicate the side walls 10 and 11 one of two end walls forming the smelting chamber, said walls preferably inclinlng inwardly and upwardly in, order toprevent hanging of material in the chamber. a chamber formed by walls 10 and 11 is closed by a cover arch 12 preferably with charging.

holes 13 and closures 14C therefor.

A short distance abovethe floor 15 of the V smelting chamber-the side Walls are perforated with a series of passages 16 leading to 2 a chimney duct 17 formed between the outer face of wall 10 and a parallel wall 18. Paralleling all 18 is a wall 19 which, with wall; 18 forms an air supply duct 20 the upper end of which is connected by'pipe .21 to a suitable source of air blast. f v I Leading from the lower end of duct 20 are several ducts or tuyeres 22, conveniently an inverted channel shaped passage of fire brick,

extending across the chimney and into and B through perforations 16 so that their discharge ends are presented into the smelting chamber. These ducts or tuyeres are considerably smaller, in cross-section than perforations 16 so as to leaveample areas for outlet of combustion gases from the smelting chamher. Tap holes 25 are provided for draining I the smelting chamber.

In operation the smelting chamber will'be initially heated by a suitable fire stimulated i by blasts through tuyeres 22. Thereupon a bed of fuel is formed and upon this bed is charged a mixture of fuel, flux and ore to be smelted and air blasts established through the. tuyeres into'the smelting chamber. The top,

m5 of this chamber will be kept closed and all outlet of gases from the chamber will be The 1; A smelting furnace comprising a main chamber formed by bounding walls and a i normally closed top, a chimney duct formed alongside one ofsaid walls an air supply duct 7 7 formed alongside the chimney duct and subducts connecting the smelting chamber and chimney, said ducts being of larger cross- 0 sectional area than the tuyeres and said tuyeres lying therein.

In witness whereof, I, OSCAR POTTER, have hereunto set my hand at Downers Grove,
